The C99 standard says that real operands aren't converted to complex, but
as I note in bug 24581, the compiler doesn't expect PLUS_EXPR and
MULT_EXPR to have argume

Hi,
I need to write a program that can interface itself
with the C preprocessor.
On the Internet I've found a lot of documentation, but
all on the C compiler and other layer of Gcc (SAT
ecc.).
I have to use the preprocessor to retrieve the
inforfations about "#pragmas" in the C code.
I think that

Hi there
i'm currently trying to set up a port for a simple RISC (actually it

Since i'm inexperienced with GCC (messed around with SUIF/Machine-SUIF
for some time) i have some questions. First of all
The runtime of what, gcc or fixincludes? Whatever solution we come up
with, I'd like to avoid duplicating setting STDC_0_IN_SYSTEM_HEADERS,
i.e. bad idea to do it once in gcc and once in fixincludes. Better is
if we can include the target config file somehow.

If it fails, then fixincludes knows we have stdc_0_in_system_headers.
